To all"; whom it may concern:

Be it @ovvn that l, Wrnnrnrr To DUGGAN, e citizen of the United States, residing at Clevelend, in the county. of Guyehoga and State of Uhio, have invented certain new and useful Improvements in Interchangeehle end Removahle Truck-Bodies; and it do herehy declare the following to he a full, clear, and exact description oi? the invention, such as "will enable others skilled in the ert to which it epperteins to make and use the same,

This invention relates to vehicles and more particularly to motor trucks, end the primary object of the invention is the pro vision of a plurality of detechahle and interchangeahle bodies for a motor truch chss sis, so that one of the hodies can he loaded with material, While the truck is hauling" another loody, thus saving time, expense and lahor. 1

Another object of the invention is the provision of a plurality of interchangeable truclr hodies for a inotor truck chassis having a plurality of rollers mounted thereon for engaging ll beams mounted on the chas sis, so that the body can he conveniently rolled on and on the chassis.

A. further object of the invention is the provision of a plurality of .loldahle legs mounted on the truck hody having rollers on their lower ends, whereby the hodies can he removed from the chassis and supported in an elevated position and moved from one place to another.

A still further oloject oi the invention is the provision of a plurality of interchange ahle fist bodies for u dump motor truck hav ing means for moving the bodies on? and on the chassis.

A still further oloject of the invention is the provision of means for autometicully moving the supporting legs downwardly in their extended position when the body is re moved from the chassis.

A still further ohject oi the invention to provide a device of the ahove character, which is durahle and eilicient in use, and one that is simple and easy to manufacture,

l, he

' and one that can he placed upon the market at a reesonehle price.

With these and other ohjects in view, the invention consists in the novel construction, formation and arrangement oi parts es will he hereinafter more specilioelly and claimed, and illustrated in the eccompanying drawings, forming a part thereof in which:

Figure l is e side elevation of e. motor dump truck having a loody mounted thereon constructed in accordance with this invention Fig. 2 is a trensverse section telen on the line 2-2 of l,

Fig. 3 is e transverse section telren on the line 33 cl Fig. l,

Fig. l is e fragmentary longitudinal section through the truck and hody,

Fig. 5 is an end elevation of the truck and hody,

6 is a deteil side elevation showing one of the rollers end the menus tor looking the body to the chessis,

l iu. is s fragmentary side elevation showing one of the rollers engaging the l beams of the chessis, end

l ig. E3 is a side elevation one of the sup-- porting legs in its lowered position.

Referring to the drevvin s in detail, wherein similar reference numerals designate corresponding parts throughout the several views, the numeral 1 generally indicetes the improved motor dump truclr having; a loody 91 positioned thereon. The motor truclr 1 includes a chassis 3, the front Wheels 4, the driving Wheel 5 and the engine 8. The chassis 3 has mounted thereon, a hoisting drum 7, which is operatively connected to the driving" shaft (not shown by a suitable clutch, (not shown). 7 The hoisting column 8 includes the pulley 9 and a hoisting cable 10, which extends from the Windin drum 7 over the pulley 9 down to the ho y. Secured to the chassis 3 and extendiinzglongitudinally of the same is e pair cl? spaced l heains ll, which receive the rollers 12 carried hy the loody E2. "llhe rollers 12 are rotetahly supported on pins 13 carried by the depending" heanos l l, which extend the Whole length of the hody, and lugs 15 which form hraclrets. The heanss it end 15 are secured to the under surlace of the hotly end positioned on such side of the it heains ll and extend slightly below the upper surface of the same end lid lllld llltl Sll all

Eli

till! 16, the side walls 17 and the end walls 18. A hoisting arm. 19 is secured to the central portion of the forward end wall 18 and is preferably formed of two sections 20 and 21 which are hingedly connected together as at 22. The section 21 projects below the under surface of the floor of the body 2 and has an eye 23 formed in its free end, whlch is adapted to detachably receive the free end of the hoisting cable 10. The arm 20 as shown in Figs. 1 and 4 is in its extended position and the section 21 cannot be thrown back any farther, but when the bodv is to be removed from the chassis, the section 21 is swung upwardly away from the hoisting drum to the under surface of the body.

Adjacent the rear end of the I beams, are secured upwardly extending brackets 24, which are suitably apertured and the apertures detachably receive the free ends of the pins 25, which support the rollers 26. The outer ends of the pins 25 are carried by the beams 14. Cotter pins 2'? extend through apertures formed in the free ends of the pins 25 and hold the same in position. The pins 25 hold the body 2 on the chassis and also form av suitable pivot for the body when the SiHHG lS to be dumped. ll hen it is desired to remove the body from the chassis, the pins 25 are slid from the tures in the brackets 24, which allows the body to be rolled 0d of the chassis.

Pivotally secured to the beams 14 are 28, which rotatably carry rollers 29 at their free lower ends for engagement with the ground. The legs 28 are arranged in pairs and one of the pairs are secured adjacent the front end of the body 2 by means of pivot pins 30, and the other pair is secured at the rear end of the body by pivot pins 31. Suitable cross braces 32 extend from one leg to the other and the cross braces are connected by diagonal brace rods 33, thus a rigid brace structure is formed for the legs. The rollers 29 are mounted on pins 34, which have one of their ends journaled in the leg and the opposite end in a bracket 35 secured to the leg. Suitable braces 36 are pivoted to the inner sides of the beams 14 and are connected to the legs 28 by means of pivot pins 37 which are rig;- idly secured to the legs and extend through a slot 38 formed in the braces. A notch 39 is formed at the lower end of the slot 38 and receives and holds the pin 37 when the legs are in extended position. The rollers 29 rest on the top of the l beams 11, which are curved downwardly at their outer ends as at 40 and as the body 2 is pulled ed" of the chassis, the legs 28 drop downwardly in their extended position by their own weight.

A suitable bracket 41 having an eye 42 formed therein, is secured to the inner sides naeaeea hoisting arm 20 and is passed around the guide pulley 43 and. around the guide pulley 14: secured to the chassis adjacent the rear end thereof, and then to the bracket it.

From the :t'oregoing description, it can be seen that an improved motor truck has been provided, which is adapted to detachahly receive a plurality of bodies, so that while one body is being loaded, another body can be emptied.

lily invention has been shown applied to a dump motor vehicle but it is to be under stood that the same can be applied to any type of motor tract s.

in practice. it have found that the of my invention, illustrated in the accompanying drawings and referred to in the above description, as the preferred embodiment, is the most eiiicient and practical; yet realizing the conditions concurrent with the adoption of my device will necessarily vary,

if desire to emphasise the fact that various minor changes in det of construction, proportion and arranp ment of parts may be resorted to, when required without sacridoing; any of the advantages of my inven" tion as set forth.
